Design ONE completely solid single-piece flat lid. No gaps, no slots, no cut-outs except those listed. Units cm, FDM print. Size 10.0 x 3.5 x 0.3 (matches the outer footprint of a box 10.0 x 3.5). Holes: (1) ONE round hole dia 2.4 at exact centre (X=5.0, Y=1.75) for a 2.3 cm test tube, 0.05 chamfer on the top edge. (2) FOUR M3 countersunk holes, dia 0.32, at (X=0.6, Y=0.6), (X=9.4, Y=0.6), (X=0.6, Y=2.9), (X=9.4, Y=2.9). Underside: a thin locating lip 0.15 high x 0.15 wide, outline 9.4 x 2.9 centred (sits inside a 9.6 x 3.1 cavity with 0.1 clearance), with a 0.8 x 0.8 square notch at each corner so it clears the corner screw posts. Top surface flat and plain. Export STEP + STL.
